Who says buffet won't lose money? Now many small cafeterias are operating at a loss. Except for a few chain cafeterias with good reputation, many others are also struggling.

For example, some large five-star hotels, due to the lack of scattered customers, the daily food expense rate has reached more than 60%. Counting labor costs and utilities, we won't make money, but enliven our popularity as hotel accessories for in-house guests.
